' 1T-his :inventionvlrelates--to r#metallic threshold '.constructionsdortdoor :saddles: "It isJ an object .=o'f the 4iinvention#toaprovide an Y`improved secftionalvdoorgsaddle,1the-parts of which Vmay `be .15 -readilyLassemble'deandftakenfapart; VItis a further object`- ito make lthe connecting -means for the several sections `'ofistandardconstruction, ysothatl-dilierentcombinations'and sizes of parts `z-:maybeused-to provide -different typesand sizes of-door saddles.

{In the -pastit `has beenlthe practice to'make Jmetallic door lsaddles, 'or `vthresholds, yof bronze strip materialfofspecial cross Vsectional shape. These lshapes havegusually Abeen made by an `lextrusion method, and, as'is'well known, such "methods 'impose idenite `limitations as to the maximum size *of ithe resulting product. Thus, there has been-adefinite limit `to 'the width of A'metal thresholds'which havebeenl made by the .2O-extrusion process in Ythe past.

`It -isv an object of the v:present invention to make'the *door'saddleof va plurality of sections sozas to remove this. size limitation.

*It is a further .objectto makethe several sec- 25-'tions ofthe saddlein 'such `a manner that Veach may Seek its own supporting oor level, by' relai tivemovemen't with the others, and independ- Vently .of 'the others. "In order'to accomplish this objectf preferably provide a pivotal connection 130.between'thesections, so that one section may move somewhat with respecttolthe other.

"The section I`I may be held in place by conventional wood screws I5, or any other suitable fastening elements.

The inner edge of the side section II is pro-.:5 vided with a longitudinally extending, cross sectionally rounded re-entrant groove I1, and the central section adjacent its edge I8 is provided with an outwardly projecting, cross-sectionally Vrounded rib or bead I9, joining the section by'flO a restricted neck portion 20. Thusthe sections I0, II may be assembledbefore Ythe saddle is put in place in the doorway, by sliding the bead I9 lengthwise into the groove Il. When thus assembled, the parts can only be taken apart`=l5 by a similar endwise movement, because the cooperation between the restricted mouth of the groove and the narrow neck of the beaded portion prevents transverse movement of the parts.

The central tread portion I0 may conveniently" 20 be provided with anti-slipping means, such as the grooves 2I, but, Aof course, any equivalent elements could be used. The inner edge 22 of the tread sectionA may be supported by simply lresting upon the side section I2, after the manner '.25 disclosed in the aforesaid patent, or a construction similar to that disclosed in Figure 6, and described below, could be substituted.

It should be noted that the upper surfaceof the central section I0 adjacent the edge I8 is 30 substantially ush with the upper section II of the section II. Wood screws 23, 24 or .the like, maybe used to hold the sections IU and I2 in place.

As a result of the pivotal connection between I the outer section II and the central section Ill,

. the saddle construction of the present invention ing or reconstructing old buildings, Where it is often -found that-the oor levels inside and outside of a door neither match each other nor the .level ofthe sill.

The form of the invention shown in Figure 2 comprises a central tread section -26Iadapted to 55 be positioned on the sill beneath the door 21. 'Ihis member comprises upper horizontally extending flanges 28, 28, serving to give a substantial width to the tread. Below these flanges the vertical faces of the section are provided with longitudinally extending circular grooves 29, 30. The inner groove 3l) receives a marginal bead 3l of the inner side section 32. The latter section may terminate at its opposite margin in a down-turned portion 33 having relatively sharp teeth 34 on its undersurface, to grip the floor. The inner groove 29 may receive the elongated bead 35 of the side section 33 which substantially fills the space between the door 21 and the screen door 31. The undersurface of the section 36 adjacent the outer margin 38 may be provided with serrations 39 adapted to cooperate with complemental serrations 4I) formed on the upper surface of an end member 4l.' The latter acts as an abutment or jamb for the screen door 31.

The form of the invention shown in Figure 3 is substantially the same as that shown in Figure 2, with the exception that, for the side section 33 and end section 4l, a simple, one-piece side section 42 has been substituted. Asindicatedin dotted lines at 43, 44, various sizes of side sections may be combined with the central tread section 2B. All of these members are provided with standard sizes of beaded edges 3l, 35 and the tread sections 25 are all provided with standard grooves 29, 3l). Therefore, :any desired sizes of side plates 32, 42, 43, 44 may be combined with a tread section of the type shown at 26 to produce different types of saddles. 'Ihe pivotal connection between the side plates and the central tread sections in all cases, will enable the saddle to compensate for differences in the n from the member 26 principally in that thel groove 46 is raised somewhat, and the kupper surface 41 of the side section- 48 is substantially iiush with a beveled portion 49 merging with the tread surface 5l). This eliminates the flange 28 on the outside of the door sill, when an vinwardly 'swinging door 5l is used, Some home owners object to an upstanding outwardly projecting flange ona door saddle because the same sometimes constitutes a stumbling block.

The form of saddle shownin Figure 5 is particularly useful in connection withk inwardly swinging French doors. The main treadsection 55 is provided with an inwardly projecting flange 56 adapted to -cooperate with the weatherstrip 51 on the door. An upwardly opening enlarged groove 53 serves to catch and collect any water which may be driven over thesill and beneath the door. Apertures 59 at the bottom of the groove provide means of egress for such water, and it should be noted that these apertures' eX- tend to the outside of the saddle so that the `water does not get into the interior of the buildy described.

Eil

The form ofy the saddle shown in Figure 6 is particularly useful for two-directional swinging doors which do not require a jamb or abutment surface. Thecentral tread section 5l] is providedwith beaded edges 6|, 62 which function in a similar mannervto the beaded edges' previously described. Side sections 63, 64 have their -inner'faces provided with grooves 65, 66, to re- .Moreoven the connection, comprising 'a reentrant groove on one section and a complemental rib on the other, prevents separation of the sections except by relative endwise movement, so that there is no danger of the sections coming apart: after they have been assembled and placed in position in the building.
